Spray nozzle is missing
Product arrived on time however when I went to remove the cap and the spray nozzle was missing. Without a nozzle the product is useless. Very disappointed.

5.00 out of 5 stars reviewVerified Purchaser09/05/2022Perfect for Window A/C Units!This is an absolute must if you use window a/c units! Just spray it on the front coils, let it soak in, and then get you a spray bottle with warm water, and watch that nasty dirt float right out the back! Cleans the entire a/c unit. Will clean the front coils, cleans out the flow hole that runs from front to back, then once it gets in the back of the unit, the slinger ring will sling the cleaner all over the back coils and clean them as well. I buy many cans of this every year in the spring to get my units ready for the summer. Price is great for what you get and the cleaning you get! WILL BUY AGAIN!!! Thank you!MeInDallas

4.00 out of 5 stars reviewVerified Purchaser06/27/2022Would be great if there were no fin guardsPositives: One can almost covered 2 AC condenser units. Seemed to clean the fins (note: the units were washed about a month prior). Easy cleanup (note2: the instruction say no rinsing is needed but I hosed the coils anyway after allowing the foam to sit about 15 minutes). Less than positives: The foam is hard to thoroughly cover the coils since the AC fin guard blocks the spray. Would be better if the foam would flow down a bit after being sprayed. This would cover areas that were blocked.Unknown

5.00 out of 5 stars reviewVerified Purchaser07/27/2021Easy to use, a great results.Our 4year old portable air conditioner had a horrible smell when on, I drained it but still had that bad smell. I actually started looking around for a dead mouse. When I determined there was no mouse, I did some research. I watched videos and read HVAC blogs, when I was satisfied the coils need cleaned, I found this product at Walmart. Came home from work poured myself a glass of wine, got my thesaurus so I had a variety of swear words at hand then took the unit to the front porch. I instantly found out I could not remove the vented casing to get to the coils as the video showed, (Glad I had that thesaurus) so I shook the can and sprayed into the vent that covered the coils and hoped for the best. I let it sit for about a half hour, then plugged it in and I'm thrilled to report the smell is gone. It has been replaced with a nice citrus fragrance. I thought I was going to have to replace the whole unit, but this can of coil cleaner saved me hundreds of dollars. I do recommend it.Debi

5.00 out of 5 stars reviewVerified Purchaser06/14/2021Easy a/c maintenance.I use Frost King a/c coil cleaner every year and several times throughout the summer on the a/c coils inside my house to keep the a/c running at peak performance. It's easy to use . Spray and done. And keep replace filler also as needed.James

2.00 out of 5 stars reviewVerified Purchaser05/14/2021No change in A/C efficiency for meI thought this product might increase the efficiency of my automobile air conditioning: it did not affect the a/c temperature; there was no change in cooling, but the a/c fins are clean .David

5.00 out of 5 stars reviewVerified Purchaser05/09/2021Saving money by cleaning A/C coils myself.HVAC company wanted $790 to clean two outside coils. I did it in 40 minutes at a cost of less than $18. Good value for the money. Coils now very clean.Christopher

5.00 out of 5 stars reviewVerified Purchaser04/25/2020I would whole heartily reccommendcleaned mold, crud and other items from coils in roof airconditioner. Also special design on cap re-opened bent or closed fins. Trailer is 4 yrs old and airconditioner has never been cleaned until I bought it. Great product.bruce

5.00 out of 5 stars reviewVerified Purchaser09/12/2016Frost King Air Conditioner CleanerThis cleaner works amazingly well. I sprayed the unit with the jet nozzle of a hose and then sprayed it well getting in the vents with the Frost King and shot down from the top against the sides as much as possible,(the fan kept spinning). I let it sit for about 20 minutes and sprayed it down with the hose again. It is sparkling clean inside and out. It has only been sprayed with water for the last 20 years this is the first time I used a cleaner on it. I am so happy with it.BettyEllen

5.00 out of 5 stars reviewVerified Purchaser04/30/2014Worked Great!Last year I cleaned my window units with hot water and a toothbrush. Tedious! So this spring I decided to try something else. The directions say to just spray it on and leave it, but I was skeptical. I sprayed it on, waited about 10 minutes and wiped all the 'gunk' off with a paper towel. Super easy!madison72997
